动压条件下采区硐室底臌机理及支护技术研究

Research on chamber floor heave mechanism in mining area under dynamic pressure and its support technique

结合东一B组轨道上山上部变电所底臌治理工程对采区硐室底臌诱发机理进行分析研究,采取新型网壳与U形钢联合支护的方案,从而解决了动压条件下硐室底臌的问题,达到了使硐室底板变形在允许范围内的效果。

By combining with the analysis and research on the inducement mechanism of the chamber floor heave in the mining areas for the floor heave treatment project in upper substation of East-B track, the paper adopts the scheme of the new reticulated shell and U steel combining support, so as to solve the problems of the chamber floor heave under the dynamic pressure, and achieve the floor heave deformation in the permitted scope.
